Nervos is a layered crypto-economy network. Nervos separates the infrastructure of a crypto-economy into two layers: a verification layer (layer 1) that serves as a trust root and smart custodian, and a generation layer (layer 2) for high-performance transactions and privacy protection. This document provides an overview of the Nervos Common Knowledge Base (CKB), a public permissionless blockchain and layer 1 of Nervos. CKB generates trust and extends this trust to upper layers, making Nervos a trust network. It's also the value store of the Nervos network, providing public, secure and censorship-resistant custody services for assets, identities and other common knowledge created in the network. The Nervos Common Knowledge Base (Nervos CKB for short) is a preservation focused, "Store of Assets" blockchain. Architecturally, it's designed to best support on-chain state and off-chain computation; economically, it's designed to provide sustainable security and decentralization. Nervos CKB is the base layer of the overall Nervos Network.

Nervos Network是一个开源的公链生态系统和协议集合。
Nervos CKB（Common Knowledge Base）是Nervos Network的基于PoW的第一层公链协议。在允许任意加密资产获得安全性、稳定性和无需许可性的同时能够支持智能合约、第二层扩容方案，并且通过“价值存储”的加密经济设计使得原生代币CKBytes捕获整个网络的价值。

CKByte (CKB)代币是该网络的原生代币并具有以下用例：
网络状态存储：CKB以字节为单位代表单元容量，它们使代币拥有者能够占据区块链整体全局状态的一部分。例如，如果用户拥有1,000个CKB，他/她就可以创建一个容量为1,000字节的单元，或者创建多个容量总和为1,000字节的单元。然后他/她就可以使用这1,000字节来存储资产、应用程序状态或其他类型的常识。
矿工补偿：以CKB代币的形式向矿工提供区块奖励和交易手续费。
股权奖励：CKB持有人可以将其原生代币存入并锁定在一个叫做NervosDAO的特殊合约中，以赚取抵押奖励。
